You are especially skilled at using a certain weapon, one that can benefit as much from Dexterity as from Strength. Choose one light weapon. Alternatively, you can choose a rapier, provided you can use it in one hand, or a spiked chain, provided you're at least Medium-size.

Choose one type of weapon, such as greataxe. You are especially good at using this weapon. You can choose ""unarmed strike"" or ""grapple"" for your weapon for purposes of this feat. If you are a spellcaster, you can choose ""ray,"" in which case you are especially good with rays, such as the one produced by the ray of frost spell.
